Spring+hibernate Integration

Is the DAO inherits the Hibernatetemplate class, which provides the Sessionfactory () method for injecting Sessionfactory

When you get DAO through spring, inject sessionfactory

Pojo class

1  PackageCom.how2java.pojo;2  3  Public classCategory {4  5      Public intgetId () {6         returnID;7     }8      Public voidSetId (intID) {9          This. ID =ID;Ten     } One      PublicString GetName () { A         returnname; -     } -      Public voidsetName (String name) { the          This. Name =name; -     } -     Private intID; -     PrivateString name; +}

DAO

DAO inherits Hibernatetemplete, and in the Hibernatetemplete class there is a setsessionfactory for the injection of sessionfactory

Package Com.how2java.dao;import Org.springframework.orm.hibernate3.hibernatetemplate;public Class CategoryDAO Extends hibernatetemplate{}

Writing Applicationcontext.xml

The sessionfactory is injected when the DAO is created, and the data source DS is injected when the sessionfactory is created
